Protects you personally from faults in the extension... like after you've left the extension run under your garage door for five months and the neutral wire is broken. For example.

Re: Forget Hydrogen

You are right, Jwax.

Re: Forget Hydrogen

No, I think if they're using potassium hydroxide as an electrolyte, it will plate out onto the negative electrode, and then instantly react with the water to make potassium hydroxide again, plus the hydrogen, which bubbles out of the equation and the cell.<p>K + H20 --> KOH + H<p>You're right about ...
